So these two pages were up for a little, but it looks like they're down now... Disney booth exclusive is Future Foundation in the white costumes- Ben, Sue, Reed and Spidey. Sue is all blue/clear and the pic on the back shows Reed with his stretch base.

Stormbreaker Thor set is exclusive to AFX, these are the shadows they teased with- Thor, Loki, Sif and Bill. The Bill has a sculpted face like the gators, not just a tampo like Lizard.

Not sure why they took them down, but i'm sure they'll be back up soon. Just had packaging pics front and back for both.
